The World: Ohio - TrimSpa announces it has created a 'TiVo-proof' ad

TrimSpa, the US diet products-maker, is preparing what it claims to be a "TiVo-proof" commercial following the death last month of Anna Nicole Smith, who previously fronted its advertising.

To maintain its profile, the company has produced an ad featuring more than 400 "before" and "after" pictures of TrimSpa users. It claims the pictures will be presented so as to show up when PVR users fast-forward through the ads.
